在运行时，锅炉板受到锅内水与蒸汽的压力作用，同时又受到火焰或烟气的烘烤或冲刷，以及锅水和烟气中有害物质对钢材的腐蚀，其工作条件恶劣。
At run time, boiler plate pressure exerted by the water and steam, but also by flame or smoke baking or flushing, and boiler water in flue gas and harmful substances on the corrosion of steel, its working condition is bad.
其中主要是通过在整个生产过程中的工艺控制使最后得到的产品具有良好的焊接及冷弯性能、一定的高温强度和耐碱性腐蚀、耐氧化等。因此对锅炉钢的性能要求比较严格，要同时拥有多种优良工艺性能和良好质价比以保证机组安全可靠运行。
Which is mainly through the entire production process control so that the resulting product has good welding and bending performance and a high temperature strength and alkali resistance, corrosion resistance and oxidation etc.. Therefore, the boiler steel performance requirements are more stringent, at the same time to have a variety of excellent technical performance and good quality to price ratio to ensure the safe and reliable operation of the unit.
由于锅炉钢板处于中温高压状态下工作，除承受较高压力外，还受到冲击，疲劳载荷及水和气的腐蚀，因此对锅炉钢材的性能要求比较严格。
Because the boiler plate is working under the condition of high temperature and high pressure, in addition to bear high pressure, but also by the impact, fatigue load and water and gas corrosion, so the boiler steel performance requirements are more stringent.
通常锅炉使用的是中厚板，其材料有平炉冶炼的低碳镇静钢或电炉冶炼的低碳钢，含碳量Wc在0.16%-0.26%范围内。制造高压锅炉时则应用珠光体耐热钢或奥氏体耐热钢。
Usually use the boiler plate, the material has low carbon steel low carbon steel smelting furnace or electric furnace smelting, the carbon content in the range of 0.16%-0.26% Wc. Application of pearlitic heat-resistant steel or austenitic heat-resistant steel when manufacturing high pressure boiler.

Q245R锅炉板轧制工艺的制定和技术措施上，充分结合炼钢厂铸机台数多，坯料规格多，可灵活进行组坯轧制的特点，在满足压缩比的条件下，实现了轧制道次的优化，减少了控轧时间对产量影响的不利条件，合理的制定了既能确保钢板性能要求，又不影响轧机能力发挥的坯料配置。
The formulation and technical measures of Q245R boiler plate rolling process, fully integrated steel plant casting machines, material specifications, flexible features of group billet rolling, to meet the compression ratio, realize the optimization of rolling times, reduce the time of controlled rolling and unfavorable conditions for yield, reasonable the formulation ensures that the steel performance requirements, and does not affect the ability to play the rolling stock configuration.
